FIFTH-=WHEEL FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 397,739, dated February12, 1889.

Application filed October 26, 1888.

To aZZ whom it may concern:

Be it known that I, JAMES MCCAULEY, a citizen of the United States,residing at Auburn Park, in the county of Cook and State 5 of Illinois,have invented certain new and useful Improvements in Fifth-Vheels for Vehicles, of which the following is a specification. The object of myinvention is to improve and. cheapen the construction of fifth-wheels,and this I do by constructing the upper member of the fifth-wheel, thebottom plate of the i bolster or head-block, and the shank forconnecting the bolster to the reach integrally, all as hereinafterdescribed, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is f a perspective view showingthe front side of 1 the bolster and axle and tho fifth-wheel. i Fig. 2is a side elevation, partlyin section, of the same parts. f

In the drawings, A represents the upper 1' member of the fifth-wheel,which is formed in- I tegrally with the bolster-plate B and a curvedshank, O, which is connected to the reach D. i This shank may have itsouter'end bifurcated, l as shown in Fig. l, where a divided reach isemployed; or it may be adapted for securement to a single reach. Iprovide flanges c on the shank projected downwardly from the sidemargins of the straight portion of the shank and embracingthe sides ofthe reach. These flanges prevent the end of the reach from splitting andgive additional strength to 1 the structure. The lower member, E, of thefifth-wheel has a curved brace, F, secured thereto, the said braceextending beneath the axle and terminating in a shank, G, secured 1fifth-wheel.

to the reach by bolts H, which pass through the shank C as well. In thisconstruction I employ a clip king-bolt, I, the clipsz'iof which 40embrace the axle and are secured thereto by a clip-tie, J, which has abearing for the stud K, which is passed through the curved brace F, andturns freely therein. The upper end of the king-bolt passes upwardlythrough the axle and is secured by the head i.

Heretofore in the construction of fifthwheels for vehicles the reach hasbeen curved or arched upwardly in the rear of the bolster and mortisedinto thelatter, and the shank has been welded to one of the members ofthe The result has been that while a considerable amount of material wasused the requisite strength was not. thereby obtained. By myimprovements the maximum strength of the material is secured at a lowcost of construction, and .I produce a fifthwheel and reach constructionsuperior to any new in the market, and in which I am able to use astraight reach.

I claim In a running-gear for Vehicles, the combination, with a lowerfifth-wheel plate clipped to the axle, of an upper fifth-wheel platehaving a bolster-plate and curved reach con structed integrallytherewith, and a clip king-bolt secured to the axle and extendedupwardly through the bolster-plate and spring, substantially asdescribed.
